I wouldnt take it as a sign of anything. Take it for exactly what it was, a positive interaction with her. Two in one day, my friend, its been a good day!
Now you need to not undo whats happened here. Wait for her to talk to you, and play it cool for a day or so.
Cling to hope: Maybe this is a chance for you to do some personal growth and practice patience! I firmly beleive that my whole situation was a big chance for me to grow. Honestly, when my H did visit, one of the major things that I noticed was just how little he had changed! It was actually a big turn off.
I guess I gave the wrong finger to the wrong man...
